Weight loss supplements: analyzing benefits, mechanisms, and the risks involved

This review focuses on the mechanisms, benefits, and potential risks of various weight loss supplements, which are becoming increasingly popular due to the global rise in obesity. These supplements include natural plant extracts, probiotics, prebiotics, and postbiotics. Supplements work through different mechanisms, such as suppressing appetite, inhibiting lipid and carbohydrate absorption, and enhancing energy expenditure. Popular ingredients like green tea extract, garcinia cambogia, and turmeric have shown some efficacy in weight reduction. For instance, green tea extract can decrease waist circumference, and garcinia cambogia has demonstrated modest weight loss effects in multiple trials. However, side effects, including liver toxicity, have been associated with some of these products.

Probiotics and prebiotics aid in weight management by modulating gut microbiota and enhancing metabolic health. Postbiotics, the byproducts of probiotics, have emerged as a safer and more stable option, suitable even for immunocompromised individuals. Despite the benefits, the review underscores the need for caution, as the lack of consistent regulation across regions leads to consumer confusion and potential health risks from unverified products. Further research is needed to establish long-term safety and efficacy.
